Intel Arctic Sound 1T and 2T pictured, feature 7680 EUs

Igor Wallosek has an exclusive first look at Intel’s upcoming Xe-HP-based accelerators for data centers. 

Intel Xe-HP was was one most teased products by the Intel Graphics team in the past few years. Raja Koduri has been teasing Xe-HP 1-4 tiles GPUs for quite some time now, but to this date, we have not heard anything on possible launch date of these products, nor any details on the architecture itself or upcoming product specs. Thanks to Igor’sLAB we now learn a lot more about the Arctic Sound family of GPUs.

It is revealed that Intel Xe-HP architecture has more Execution Units than previously reported. Unlike Xe-LP which has been implemented into Tiger Lake and DG1 GPUs which comes with up to 96 EUs, the Xe-HP features up to 512 EUs per tile. We already know that there are at least three variants: 1-tile, 2-tile, and 4-tile. The three listed two card models have been confirmed by Igor, along with their photos and specs.

Intel Arctic Sound 1T

Intel Arctic Sound 1T refers to a 1-tile configuration of 512 EUs, but this model has some part of the graphics silicon disabled. That said only 384 EUs are enabled. If we assume that Xe architecture follows the same principle as previous generations, then we could say that this model has 3072 shading units (ALUs/cores you named it). This card is also equipped with 16GB of HBM2e memory. Igor reports that this model has 150W TDP, which is lower than the previously reported 225W, but that number must have applied to the full 512EU 1-Tile, which this card simply is not offering. Finally, Arctis Sound 1T has a PCIe Gen4 interface.

Intel Arctic Sound 2T

A dual-tile Xe-HP model has 480 EUs per tile. This means that the card has 7680 shading units in total, but it still not the full 8192 configurations. The 2T model has 32GB of HBM2e memory and a TDP of 300W. It makes use of a single 8-pin EPS connector, which is actually becoming a standard for data centers and workstation graphics cards.

It is reported that four tile Xe-HP SKU is nowhere to be seen yet, which implies that there are some issues with the production. The information that was shared by Igor is based on Intel internal slides which were not published in order to secure the source. The images of the Xe-HP graphics cards were upscaled using AI software.
